This invention relates to a separator for the ring rail of a twister.

In the operation of twister-s at high speed the strands of yarn or other material tend- 5 o balloon in the vicinity of the rings. Suchb ballooning action causes adjacent strands to interfere. To correct or avo1d the ballooning action of the strands it has been usual heretofore to provide windshield separators or vanes upstanding on the ring rail between the rings. In order to keep the weight of the ring rail within practical limits it has been necessary to make such windshield vanes of light material so that in handling or in the operation of threading the yarn through the rings the windshield separators become bent thereby rendering them useless or making it necessary to replace them. In addition due to the fact that windshield separators provide support for the strand only on two sides, v-erv uneven wear of the ring results from the motion of the traveller on the ring as the strand passes therethrough.

It is the obiect of this invention to provide an improved form of separator which will fur her l m t the balloonin of strands, which will afford support to the windshield type of separator. and which will prevent to a large eYtent such uneven motion of the varn or strands as causes uneven wear in the rings.

Other advantages of the present invention will appear in the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a pers ective view of the preferred embodiment of this invention;

Fig. 2 is a plan view of the device shown in Fig. 1.

In the drawings the numeral 1 designates the ring rail of a twister having rings 2 on which travellers (not shown) are carried. In operation the yarn passes through the eye of the traveller, the traveller being free to move around the ring. In order to prevent adjacent strands from interfering with each other due to ballooning, the upstanding vanes or windshield separators 3 are mounted on the ring rail 1 between the rings 2. The construction so far described is well known the art and no claim of invention is made to-thatstructure per se.

In the operation of twisters at very high speedsuchasSOOO R. P. M. the ballooning ecomes excessive-even when windshield sep- .arators are employed. According to this invention excessive ballooning at high speeds is prevented'by the wire frame 4 having the loops 5 formed therein which engage the vanes 3 as shown in the drawings. The loop 5 providessup'port for the strand of yarn as it passes to the follower upon the ring 2 for the major portion of the circumference of the ring. The loops 5 are open in the front as shown clearly in the drawings only for the purpose of facilitating the insertion of the yarn therethrough. The distance of approach between the legs 6 forming the front portion of the loop may be varied to any degree desired, thus providing more or less support for the yarn at that side of the ring. Of course it is obvious that the loops 5 may have other shapes than a circular one and still perform the function of supporting the yarn satisfactorily. In addition the wire frame 4 serves as a strengthening support for the vanes 3 thereby adding to their usefulness and life. The additional support afforded to the yarn by the frame 4 also removes to a large extent the excessive local wear upon the rings 2 which is usual when only separators of the Windshield type are provided.

While one form of the invention has been described in detail, it is obviousithat modifications may be made therein without departing from the scope of the invention indicated in the following claims.

Having thus described my invention, what I claim and desire to protect by Letters Pat out is:

1. A separator for ring rails which comprises vanes upstanding on said rail between said rings, and a wire strand frame forming a plurality of loops said loops being arranged between the vanes and adapted to guide a strand.

2. Separators for ring rails which comprises vanes interposed between said rings and upstanding on said rail, and a wire frame having a plurality of loops positioned between said vanes, said frame being clamped on said vanes.

3. Separators for ring rails which comprises a plurality of Windshield separators upstanding from said rail between said rings, and a loop positioned between each pair of Windshield separators adapted to guide a strand and to support said windshield sepators. I

4. Separators for ring rails which comprlses vanes upstandmg on said real between said rings, a Wire frame having loops therein,

said loops being arranged between the, vanes and exercising a clamping action on said 5. A separator for ring rails which comprises vanesupstanding on said rail between said rings,' and a wire frame having loops 'ar-" ranged between the vanes adapted to guide a strand, said frame and vanes being connected for their mutual support.
